Overview



Suspension is the link between the body and wheels. Through it passed to the body forces acting on the wheel. The elements included in the suspension, soften dynamic loads, reduce body movements, provide good stability and smooth running of the car.
Beats perceived tires and suspension springs. Shock absorbers serve to convert body vibrations into heat, and the suspension, resulting in fluctuations are damped. The operating principle of the shock absorber is based on the creation of high resistance rocking body by forced overflow of liquid through the small flow areas in the valves.
Shock absorber - the main suspension - combine the function of the guide unit and blanking element. In fact, this compound spring absorber in one piece, wherein the shock absorber is inserted into the coil spring.
To the lower arm front suspension stabilizer bar is attached, which is suitably bent bar made of spring steel. It works as follows: when cornering wheel located on the inner turning radius, moving away from the vehicle, the stabilizer is twisted. The resulting spring force supports the shock absorber base, which is located at the outer radius of rotation, which, together with the springs increases the rigidity of the rack. The result of the stabilizer is expressed in a significant decrease in banks cornering. When the vehicle tilts, for example, when braking, the stabilizer is not working.

A WARNING
It is strictly forbidden to carry out welding and straightening work on the elements of the suspension. Always replace the bolts and self-locking nuts with traces of corrosion.
